Hot Air Balloon
Published on Fri 10 December 1999
Three men are in a hot air balloon. Soon, they find themselves lost in a canyon somewhere.
One of the three men says, "I have got an idea. We can call for help in this canyon and the echo will carry our voices far." He leans over the basket and yells out, "Helllloooooo! Where are we?"
They hear the echo several times. 15 minutes later, they hear this echoing voice, "Helllloooooo! You are lost!"
One of the men says, "That must have been a mathematician."
Puzzled, one of the other men asks, "Why do you say that?"
The man replies, "For three reasons: 1) he took a long time to answer, 2) he was absolutely correct, and 3) his answer was absolutely useless."
